Hi,

Just wanted to inform you that we have submitted a draft on the Hierarchical Stateful PCE. As control hierarchy has been discussed in various context, we felt the usefulness of extending stateful PCE work to hierarchical control. 

Your comments will be appreciated.

Thanks & best regards, 

Young (on behalf of Dhruv, Daniele, Jongyoon and Dan)

Abstract:
   A Stateful Path Computation Element (PCE) maintains information on
   the current network state, including: computed Label Switched Path
   (LSPs), reserved resources within the network, and pending path
   computation requests. This information may then be considered when
   computing new traffic engineered LSPs, and for associated
   and dependent LSPs, received from Path Computation Clients (PCCs).

   The Hierarchical Path Computation Element (H-PCE) architecture,
   provides an architecture to allow the optimum sequence of
   inter-connected domains to be selected, and network policy to be
   applied if applicable, via the use of a hierarchical relationship
   between PCEs.

   Combining the capabilities of Stateful PCE and the Hierarchical PCE
   would be advantageous. This document describes general
   considerations and use cases for the deployment of Stateful PCE(s)
   using the Hierarchical PCE architecture.

Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
